Prevalence and risk factors of peri-implant mucositis and peri-implantitis after at least 7 years of loading

Abstract

PURPOSE: This study examined the prevalence and risk factors of peri-implant disease after at least 7 years of dental implant loading. METHODS: A total of 111 patients with 218 dental implants were treated. The follow-up period for all implants was at least 7 years. The patients' dental records were collected and risk factors of peri-implant disease were investigated through logistic regression analysis. RESULTS: <0.05). CONCLUSIONS: Within the limits of this study, no significant correlations were found between any risk factors and peri-implant mucositis, but a significantly elevated risk of peri-implantitis was observed in patients who smoked or had splinted prostheses in 2 or more implants.
